OpenCCG: The OpenNLP library

OpenCCG, the OpenNLP CCG Library,
is an open source natural language processing library written in
Java, which provides parsing and realization services based on Mark Steedman's
Combinatory Categorial Grammar (CCG) formalism.
The library makes use of multi-modal extensions to CCG developed by
Jason Baldridge
as part of the Grok system
(the precursor to OpenCCG). Current development efforts, led by Michael White, are focused on making the realizer practical to use in dialogue systems.
For the latest news about OpenCCG, check out the
SourceForge project page.

The C&C Parser and Supertagger

The C&C CCG parser and supertagger form
part of the language processing tools developed by James Curran and Stephan Clark.
The tools are written in C++ and have been designed to be efficient enough for large-scale NLP tasks.

StatCCG

StatCCG is a statistical CCG parser (trained on CCGbank) written by Julia Hockenmaier. Executables are available here

Boxer

Boxer is developed by Johan Bos and generates semantic representations. It takes as input CCG (Combinatory Categorial Grammar) derivations and produces DRSs (Discourse Representation Structures, from Hans Kamp's Discourse Representation Theory) as output. It is distributed with the C&C tools.
